Because the same letter is never repeated four times. Six pairs put a smaller letter first so it is subtracted: IV (4), IX (9), XL (40), XC (90), CD (400), CM (900).

How to read this
- Add from the left, but subtract when a smaller letter comes before a larger one.
- There are only seven letters: M=1000, D=500, C=100, L=50, X=10, V=5, I=1.
- The same letter repeats at most three times — the fourth becomes a subtractive pair.
- There is no zero, and the largest place value is always written first.
